  • Author: Lily
  • Total Time: 30-45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 1 pound ground beef: The foundation of your burger, providing rich, juicy flavor.
  • 1 teaspoon salt: Essential for seasoning and enhancing the beef’s natural taste.
  • 1/2 teaspoon black pepper: Adds a subtle spice to balance the flavors.
  • 1 tablespoon Worcestershire sauce: Infuses the patties with deep, umami richness.
  • 2 large onions, thinly sliced: The star of the show, providing sweetness and depth.
  • 2 tablespoons butter: Used for caramelizing the onions to achieve their rich flavor.
  • 1 tablespoon olive oil: Helps to cook the onions evenly without burning.
  • 1 teaspoon sugar: Enhances the caramelization process, adding a sweet contrast.
  • 1 cup beef broth: Adds moisture and depth to the caramelized onions.
  • 4 slices Swiss cheese: Melts perfectly over the patties, adding creamy texture.
  • 4 brioche buns, toasted: Provides a soft, slightly sweet base for the burgers.
  • Fresh parsley, chopped (for garnish): Adds a fresh, herbaceous note to finish the dish.

Instructions

Caramelize the Onions:

  • Heat butter and olive oil: In a large skillet, heat 2 tablespoons butter and 1 tablespoon olive oil over medium heat.
  • Cook the onions: Add 2 large sliced onions and cook, stirring occasionally, until they become soft and golden brown, about 15-20 minutes.
  • Add sugar: Sprinkle 1 teaspoon sugar over the onions and continue to cook for another 5 minutes until they are deeply caramelized.
  • Simmer with beef broth: Pour in 1 cup beef broth and simmer until the liquid is mostly absorbed, about 10 minutes. Set aside.

Prepare the Burger Patties:

  • Mix ingredients: In a mixing bowl, combine 1 pound ground beef, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 tablespoon Worcestershire sauce. Mix until just combined.
  • Form patties: Divide the mixture into 4 equal portions and shape them into patties.

Cook the Burger Patties:

  • Heat the skillet or grill: Preheat a skillet or grill over medium-high heat.
  • Cook the patties: Cook the burger patties for about 4-5 minutes on each side, or until they reach your desired level of doneness.

Assemble the Burgers:

  • Melt the cheese: Place a slice of Swiss cheese on each patty and let it melt.
  • Toast the buns: Ensure 4 brioche buns are toasted and ready.
  • Layer the ingredients: Place the burger patties on the bottom halves of the toasted brioche buns. Top each patty with a generous amount of the caramelized onions. Garnish with chopped fresh parsley.

Serve and Enjoy:

  • Complete the burgers: Place the top halves of the buns on the burgers.
  • Serve immediately: Pair with your favorite sides like fries or a fresh salad for a complete meal.
